What I love about The Force Awakens (and what I suspect longtime Star Wars fans dislike about it) is that it treats Star Wars as myth in order to usher a new generation into that world. The movie is built on the idea that you've heard about but never bought into Star Wars, and it sweeps you along with a surprising amount of humor and some wonderfully earnest characters. The very first scene in The Force Awakens even goes out of its way to make you laugh.
The real goal of the movie is to make you believe that you can get swept away into a magical universe, and I think it nails that feeling — letting you at least briefly experience those feelings of wonder and awe along with the characters. I'm sure The Last Jedi will have to move beyond these themes, but now that I care about the world, I'm ready to see what's next.
